Here I precipitate pure zinc metal from old chemical waste using galvanic deposition via alkaline hydrolysis.
Note that I misspoke and said that the zincate ion loses electrons to reduce to elemental zinc, it actually GAINS electrons to reduce.
Materials: Sodium hydroxide, zinc hydroxide, nickel/copper electrodes, DC power supply.
Hazards: Small risk of electric shock, chemical burns from caustic strong bases
Methods: Deviation of procedure by NurdRage
